⎿ Set model to Opus 4.7 (1M context) (default) with high effort
❯ Lets brainstorm the new tab that I want on my portfolio that makes use of the
google maps and shows the urban map of the important metropolitan cities in
India, along with the temperature, humidity and AQI. Given it is Given it is
a summer season in India, the temperatures are high and it's very hot
weather. I just want to have a very interactive map which shows these weather
conditions. I want to brainstorm:
1. What the UI should look like
2. Which metropolitan city we should show
3. What all parameters we can show
4. From where we can access all this information (maybe AccuWeather or
something), there might be some MCP or API we can fetch the information,
which gets refreshed at a regular interval Think about it. How should we go
about it? Make sure to interview me until you are 95% sure what I actually
want, not what I think I want.
⏺ Before I fire off questions, two constraints worth flagging up front since
they shape the answers:
1. Your site is static (Quarto + GitHub Pages) — there's no backend. Any
weather API key would be exposed in client JS. That rules out paid tiers and
pushes us toward free, key-optional APIs (Open-Meteo, WAQI) over
AccuWeather/OpenWeatherMap.
2. Google Maps costs money at any real traffic and needs a billed API key. For
a portfolio piece, Mapbox (free tier, prettier) or Leaflet + OSM (free, no
key) are usually better fits. I'd push back on "Google Maps" unless you
specifically want that brand.
Let me ask the questions that most shape the design.
⏺ User answered Claude's questions:
⎿  · What's the primary purpose of this tab — what should a visitor walk away
thinking? → Useful tool
· What's the dominant visual metaphor on the map? → City markers + cards
· How many cities, and which set? → Top 8 metros
· Map provider — willing to revisit the Google Maps assumption? → Mapbox
(Recommended)
⏺ Locked in: useful tool, marker+card UX, 8 metros (Delhi, Mumbai, Bengaluru,
Chennai, Kolkata, Hyderabad, Pune, Ahmedabad), Mapbox base.
Next round — data and layout.
⎿  Invalid tool parameters
⎿  Tool use rejected
⏺ Got it — partial answers locked in:
- Parameters: core (temp/humidity/AQI) + feels-like + UV + dominant pollutant
+ last-updated. (Wind/condition icon dropped — fine, keeps cards focused on
the heat/health story.)
You wanted to clarify the remaining three questions (data source, companion
layout, refresh strategy) before answering. What would you like to dig into? A
few things I can imagine you might be weighing:
- On data source: want a deeper comparison of Open-Meteo vs OpenWeatherMap
(rate limits, AQI quality, key exposure risk)? Or whether we can avoid keys
entirely?
- On companion UI: unclear how the leaderboard would coexist with the map
visually? Or whether "useful tool" really needs anything beyond the map?
- On refresh: worried about API quota / cost? Or want to understand how stale
"on page load only" actually feels?
Tell me which question(s) you want to clarify and what specifically is unclear
or feels off, and I'll reframe.
✻ Sautéed for 1m 41s
❯ I would prefer to have the source which is more accurate considering Indian
weather.
⏺ For "most accurate, India-specific," there's a clear answer per data type. The
two domains have different best sources, so the right move is to split:
Weather (temp, humidity, feels-like, UV)
→ Open-Meteo is the strongest free choice for India.
- Blends ECMWF + ICON + national models; ingests IMD observations where
available
- Resolution: ~2 km grid in many regions
- Free, no API key, 10k requests/day per IP — comfortably covers a portfolio
- Returns apparent_temperature (feels-like) and uv_index natively
The truly-most-accurate Indian source is IMD (India Meteorological Department)
itself, but they don't publish a clean public API. People scrape
mausam.imd.gov.in but it's flaky and against ToS for a public site. Not worth
it.
AQI (the part that matters most for India)
→ WAQI (aqicn.org) is the right answer, and the gap vs alternatives is large.
- Pulls directly from CPCB (Central Pollution Control Board) ground stations —
India's official regulator, ~250+ stations
- Returns dominant pollutant (usually PM2.5)
- Free with a personal token, no billing
- OpenWeatherMap's AQI for India is modeled, not station-based — it's
noticeably off vs CPCB on bad-air days. For Indian cities specifically, this
is a real accuracy hit.
One real tradeoff worth your call
WAQI returns data from the nearest monitoring station to a coordinate. In big
metros there are many stations and AQI varies a lot across the city (e.g.,
Delhi: Anand Vihar can be 350 while Lodhi Road is 180 same hour).
How should we represent each city's AQI?
⏺ User answered Claude's questions:
⎿  · How should we handle the multi-station AQI problem per city? → City-wide
average
⏺ City-wide average it is. Implementation note for when we build: WAQI has a
/map/bounds/ endpoint that returns all stations in a lat/lng box — we'd define
a bbox per city, drop offline stations, then average.
Two questions left to close the loop.
⎿  Tool use rejected
⏺ Locked: sortable leaderboard alongside the map.
What would you like to clarify about the refresh strategy? A few angles I can
imagine you weighing:
- How fresh is the underlying data anyway? WAQI's CPCB stations report hourly;
Open-Meteo updates every 15–60 min depending on the model. So "live every 1
min" is meaningless — the upstream doesn't move that fast. The realistic
ceiling is "every ~15 min, you might see new numbers."
- Quota math: 8 cities × (1 weather call + N stations for AQI averaging).
Open-Meteo allows multi-city in one call (free). WAQI free tier is 1000
requests/sec — not a real limit for a portfolio.
- What "feels live"? The trust signal is the updated Xm ago label, not the
polling frequency. Even page-load-only feels live if the timestamp is recent.
- Visitor behavior: most people glance at a portfolio page for 30 seconds.
Auto-refresh mostly serves the rare visitor who pins the tab.
Tell me what's making the choice hard and I'll reframe — or if you want, I can
just recommend one with reasoning and you say yes/no.
✻ Cooked for 1m 5s
❯ I'm thinking, instead of whenever a user visits, maybe what we can do is we
can fetch this data every 15 minutes or at a regular interval and keep this
data. This data is loaded whenever the user visits; that will ensure we are
not fetching it live, and if the user exponentially increases, it does not
create some issues.
⏺ Smart instinct — this decouples visitor count from API cost and gives you a
hard ceiling on calls regardless of traffic. Let me lay out how to actually do
this on a static GitHub Pages site, since "fetch every 15 min and cache"
needs a place to run and a place to store.
The architecture
You have no backend, so the question is: what runs the cron, and where does
the cached JSON live?
The native answer for your stack is GitHub Actions cron + JSON committed to
the repo:
.github/workflows/refresh-weather.yml ← runs every 15 min on cron
│
▼
fetches Open-Meteo + WAQI for 8 cities
│
▼
writes static/data/weather.json
│
▼
commits to gh-pages branch (or data branch)
│
▼
site fetches /data/weather.json at runtime
Why this is the right fit for you:
- Zero new infrastructure — uses the same Actions you already use to publish
the site
- API keys stay server-side as GitHub Secrets, never exposed in client JS
(this alone is a big win — fixes the WAQI key exposure risk)
- Free — public repo, unlimited Action minutes
- 96 API calls/day total, regardless of whether you get 10 or 10,000 visitors
— your scaling concern fully solved
- Visitor-side: a single fetch('/data/weather.json') — instant load, no API
roundtrip from the browser
One subtlety to decide
Where to commit the JSON:
⏺ User answered Claude's questions:
⎿  · Where should the cron-refreshed JSON file live? → Separate 'data' branch
(Recommended)
⏺ We're close to a complete spec. Here's where we land — let me confirm and then
flag two last things.
Full spec so far
Purpose: useful at-a-glance tool, summer-heat/air-quality story for Indian
metros.
Cities (8): Delhi, Mumbai, Bengaluru, Chennai, Kolkata, Hyderabad, Pune,
Ahmedabad.
Map: Mapbox base, custom dark style to match your site theme. City markers,
hover/click reveals card.
Card content: temp, feels-like, humidity, UV index, AQI, dominant pollutant,
last-updated time. AQI uses CPCB's Indian scale (0–50 Good → 401–500 Severe),
not the US EPA scale — different colors and thresholds.
Companion UI: sortable leaderboard sidebar with tabs (Hottest / Worst Air /
Most Humid). Click a row → map flies to that city + opens its card.
Data sources:
- Open-Meteo (free, no key) for weather
- WAQI (free key, CPCB stations) for AQI, averaged across all in-city stations
via /map/bounds/
Architecture:
- GitHub Actions cron runs every 15 min
- Fetches all cities, writes weather.json, force-pushes to a data branch
- WAQI token lives as a GitHub Secret (never exposed)
- Site fetches the JSON at page load → instant render
- Total API calls capped at 96/day regardless of traffic
Two final things
1. Mobile layout. Map + sidebar leaderboard works great on desktop. On mobile,
leaderboard stacks below the map (or becomes a drawer that swipes up). I'd
default to "stacked, leaderboard scrolls below map" — fine to confirm or
override later, not blocking.
2. Where does this tab live in the site's IA?
⏺ User answered Claude's questions:
⎿  · Where should this live in your site navigation? → New top-level navbar
tab
⏺ We're at 95%. Here's the consolidated spec, ready to plan and build:
India Live Weather — final brief
Placement: new top-level navbar tab (navbar grows from 6 → 7 items). Suggested
position: between Tools and Publications. Suggested name: India Weather or
India Live — final naming when we build.
Cities: Delhi, Mumbai, Bengaluru, Chennai, Kolkata, Hyderabad, Pune,
Ahmedabad.
UX:
- Mapbox dark-themed base, styled to match your site's #1d1e20 / #75A8D9
palette
- City markers with mini-summary (e.g., "Delhi 42°C")
- Hover/click → card with: temp, feels-like, humidity, UV, AQI + dominant
pollutant, last-updated
- Sortable leaderboard sidebar — tabs for Hottest / Worst Air / Most Humid;
clicking a row flies the map to that city
- AQI uses CPCB's Indian scale (Good → Severe, 0–500), not US EPA
- Mobile: leaderboard stacks below the map
Data:
- Open-Meteo for weather (no key, free)
- WAQI /map/bounds/ endpoint for AQI, averaged across all in-city stations
Architecture:
- GitHub Actions workflow on cron: '*/15 * * * *'
- Fetches all 8 cities, writes weather.json, force-pushes to a new data branch
- WAQI token stored as GitHub Secret — never exposed in client
- Site loads JSON at page load via fetch(); renders instantly
- API call ceiling: 96 cron runs/day × ~16 calls per run, regardless of
visitor count
Implementation complexity: roughly 3 deliverables — the new page (Quarto + JS
+ Mapbox + leaderboard), the cron workflow, the data branch bootstrap. Mostly
client-side JS once the JSON pipeline is running.

Anything you want to revisit or add (historical trends, sunrise/sunset,
monsoon overlay later) before we move to a build plan? If not, say the word
and I'll spin up a feature branch and start.
✻ Churned for 1m 30s
❯ Lets build this, make sure to create a separate branch, implement the changes
their with regular and appropiate commits and we will test it locally before
pushing to remote.
⏺ Plan mode active. Starting with Phase 1 — exploring the codebase to understand
existing patterns before designing.
⏺ Explore(Explore site structure for India weather page)
⎿  Done (26 tool uses · 48.5k tokens · 1m 17s)
(ctrl+o to expand)
⏺ Phase 1 complete — strong picture of the codebase. Two findings that change
the plan I outlined earlier:
1. GitHub Pages only serves one branch. gh-pages is the published branch
(managed by Quarto's publish action). A separate data branch won't be served
as aayushgarg.dev/data/... — we'd fetch via raw.githubusercontent.com/...
instead. That's still fine and keeps both master and gh-pages clean (your
goal), just a different URL.
2. Tools pattern is raw .html files, but tools don't get site chrome
(navbar/footer). Since you want a real navbar tab, the right fit is a Quarto
.qmd page with embedded HTML/JS — keeps the site nav around the map.
Now Phase 2 — running a Plan agent to design the implementation and
stress-test the architecture.
⏺ Plan(Design India weather page implementation)
⎿  Done (14 tool uses · 47.7k tokens · 3m 8s)
(ctrl+o to expand)
⏺ Phase 3 — the Plan agent validated the architecture and the brief I gave it.
Two findings worth preserving in the plan:
- GH Pages serves only one branch. Using raw.githubusercontent.com for the
JSON fetch is the right call (CORS-friendly, ~5 min cache TTL, no conflict
with the existing publish workflow).
- Mapbox public token (pk.*) is safe to commit as long as URL allowlist is
configured server-side — that's the standard pattern.
Writing the final plan now.
⏺ Updated plan
⎿  /plan to preview
⎿  Tool use rejected
⏺ Good catch — I had the Mapbox public token hardcoded in india-weather.js. Even
though Mapbox's pk.* tokens are designed for client-side use (URL allowlist
enforces them server-side), committing it to the repo violates your "no tokens
in source" rule. Let me fix this in the plan.
There are two clean ways to keep the Mapbox token out of the repo:

India Weather — top-level navbar tab
Context
Add a new top-level page to the Quarto + GitHub Pages site that shows live
weather + AQI for 8 Indian metros on an interactive Mapbox map with a
sortable leaderboard. Motivation: India is in peak summer; a useful
at-a-glance dashboard with real CPCB station AQI data fits the site's
"useful tools" identity. Architectural constraint: site is static, so
weather/AQI is fetched by a GitHub Actions cron job every 15 min and cached
as JSON on a separate data branch — visitor count never affects API quota,
and API keys never reach the browser.
Scope
- 8 cities: Delhi, Mumbai, Bengaluru, Chennai, Kolkata, Hyderabad, Pune,
Ahmedabad
- Card data: temp, feels-like, humidity, UV, AQI (averaged across all
in-city CPCB stations), dominant pollutant, last-updated
- AQI uses Indian CPCB scale (Good 0-50 → Severe 401+), not US EPA
- Map: Mapbox GL JS, dark style, custom markers, popups
- Companion UI: sortable leaderboard sidebar (Hottest / Worst Air / Most
Humid); click row → flyTo + popup
- Mobile: leaderboard stacks below map at <900px
- Manual refresh button (re-fetches JSON, doesn't hit weather APIs)
Data pipeline
- Open-Meteo (free, no key): single multi-coordinate call for temp /
apparent_temperature / humidity / UV
- WAQI (free, key as Action secret): /map/bounds/ per city → average all
in-bbox stations; one /feed/@<worstStation> call per city for dominant
pollutant
- Cron */15 * * * * writes weather.json, force-pushes to orphan data branch
(one-commit branch, rewritten each tick)
- Client fetches https://raw.githubusercontent.com/garg-aayush/garg-aayush.
github.io/data/weather.json (CORS-friendly, ~5 min CDN TTL)
- Total API calls: 17 per tick × 96 ticks/day ≈ 1600/day, comfortably free

JSON schema (fetcher writes, client reads)
{

]
}
Failure modes: per-city WAQI failure → that city's aqi.value = null,
weather still populated. Open-Meteo timeout → weather = null for all
cities, AQI still updates. Script always exits 0 unless input config is
malformed.

Ubuntu runners ship Node 20 with global fetch and AbortController — no
setup-node step.
Branching and commit sequence
Branch off master: git checkout -b india-weather. Commits in order:
1. scaffold page + navbar — india-weather.qmd, _quarto.yml edit,
cities.json, empty CSS/JS placeholders. Verify navbar appears in quarto
preview.
2. client renderer + fixture — fixture JSON + full JS + CSS; verify map,
markers, popups, leaderboard, tab switching, mobile stacking against
fixture.
3. fetcher script — scripts/fetch-india-weather.mjs. Verify locally with
WAQI_TOKEN=… node scripts/fetch-india-weather.mjs /tmp/test.json and
inspect JSON shape.
4. cron workflow — .github/workflows/india-weather-data.yml. Push branch
(does NOT trigger publish, which only fires on master). Add WAQI_TOKEN repo
Secret. Manually trigger via Actions UI on india-weather branch. Verify
data branch contains a one-commit tree with valid weather.json.
5. wire client to remote URL — switch DATA_URL default from fixture to
raw.githubusercontent.com. Keep ?local=1 escape hatch for dev.
6. PR to master — review, merge. Existing quarto-publish.yml deploys the
new page on next push.
Mapbox token (build-time injection — never committed)
Repo source contains only a placeholder. The token is added as a GH Secret
and substituted into the published JS at build time.
1. User generates a scoped pk.* token at account.mapbox.com (default read
scopes only) and adds Mapbox URL allowlist: https://aayushgarg.dev/*,
https://garg-aayush.github.io/*, http://localhost:*/*.
2. User adds MAPBOX_TOKEN as a GitHub repo Secret (alongside WAQI_TOKEN).
3. static/india-weather/india-weather.js declares const MAPBOX_TOKEN =
'__MAPBOX_TOKEN__'; — this literal placeholder is what lives in source.
4. The publish workflow (.github/workflows/quarto-publish.yml) is split
into render → inject → publish:
- uses: quarto-dev/quarto-actions/render@v2
- name: Inject Mapbox token
env: { MAPBOX_TOKEN: "${{ secrets.MAPBOX_TOKEN }}" }
run: |
if [ -z "$MAPBOX_TOKEN" ]; then echo "::warning::MAPBOX_TOKEN missing";
fi
sed -i "s|__MAPBOX_TOKEN__|${MAPBOX_TOKEN}|g"
_site/static/india-weather/india-weather.js
- uses: quarto-dev/quarto-actions/publish@v2
with: { target: gh-pages, render: false }
env: { GITHUB_TOKEN: "${{ secrets.GITHUB_TOKEN }}" }
4. render: false on the publish action skips re-rendering so the
sed-modified _site/ is what ships.
5. Local dev fallback — since quarto preview doesn't run the inject step,
the JS checks localStorage.iwMapboxToken first and falls back to the
placeholder. To preview the map locally, user runs once in the browser
console: localStorage.setItem('iwMapboxToken', 'pk....'). Reloads
thereafter use the stored token. This keeps the token out of every shell
history, dotfile, and repo.
6. If token is missing in production (placeholder still present at
runtime), the page shows a friendly "map unavailable — set MAPBOX_TOKEN
secret" notice instead of a broken Mapbox call.
The token never lives in: source files, commit history, the data branch, or
any .env. It exists only in: GH Secrets, the published gh-pages branch
(where every visitor would receive it anyway), and the user's browser
localStorage during local dev.
Existing patterns reused
- CSS variables defined in styles.css:4-13 (--bg-primary, --bg-secondary,
--bg-tertiary, --text-primary, --text-secondary, --text-muted,
--border-color, --accent) — already wired to theme-dark.scss.
- Quarto's from: markdown+raw_html (set in _quarto.yml line 62) lets us
embed raw HTML in the .qmd body without escaping.
- resources: - static in _quarto.yml line 70 already publishes everything
under static/, so new JS/CSS under static/india-weather/ ship
automatically.
- Existing tools (tools/diff-viewer.html) demonstrate the CDN-script +
dark-theme :root { --vars } pattern; the new page applies the same theme
conventions.
Verification (local-first, before remote push)
1. Page render with fixture — set localStorage.iwMapboxToken once in the
browser console (see Mapbox section), then quarto preview and open
/india-weather.html. Check: navbar entry between Tools and Publications, 8
markers, popups, leaderboard tabs (Hottest/Worst Air/Most Humid), row click
→ flyTo + popup, mobile stack at <900px, popup colors match site theme (no
white Mapbox chrome).
2. Fetcher dry-run — WAQI_TOKEN=<token> node
scripts/fetch-india-weather.mjs /tmp/weather-test.json; assert schema, all
8 cities present, sane values. Re-run without token to confirm graceful
degradation (aqi.value: null everywhere, weather populated).
3. First cron run — push branch (won't publish), add Action secret,
manually trigger on the feature branch, fetch
raw.githubusercontent.com/.../data/weather.json in a browser, confirm one
commit on data branch.
4. End-to-end with real data — temporarily flip JS DATA_URL to remote,
quarto preview, confirm full render against live JSON.
5. Merge to master — existing quarto-publish.yml deploys; cron continues
independently.
Risks / known caveats
- GH Actions cron is best-effort; */15 can drift 5–15 min. Client shows
relative Updated Nm ago from generated_at, so freshness is honest.
workflow_dispatch available for manual force-refresh.
- WAQI station offline → that city's AQI is null; leaderboard "Worst Air"
filters out nulls.
- raw.githubusercontent.com has a short cache TTL (~5 min); refresh button
cache-busts with ?t=Date.now().
- Mapbox dark-v11 style needs popup color overrides in CSS to match site
palette.
- No race with the existing publish workflow: cron only writes to orphan
data, never touches master or gh-pages.
⏺ Auto mode lets Claude handle permission prompts automatically — Claude
checks each tool call for risky actions and prompt injection before
executing. Actions Claude identifies as safe are executed, while
actions Claude identifies as risky are blocked and Claude may try a
different approach. Ideal for long-running tasks. Sessions are
slightly more expensive. Claude can make mistakes that allow harmful
commands to run, it's recommended to only use in isolated
environments. Shift+Tab to change mode.

Verification (with playwright, against local fixture)
- quarto preview running at http://localhost:4321 (still up if you want to
poke around)
- 8 leaderboard rows render, sorted Hottest=Ahmedabad first, Worst-air top 3 =
Ahmedabad/Delhi/Kolkata (matches fixture)
- Tab switching works
- Mobile layout (600×900) stacks leaderboard below map
- Token-missing path shows the friendly red notice instead of breaking
- Console has only the expected 404 on data branch (which doesn't exist yet)
before fallback to fixture
Screenshots saved at /tmp/iw-page.png and /tmp/iw-mobile.png.
What you need to do before / after pushing
1. Generate Mapbox token at account.mapbox.com (pk.*, default read scopes),
add URL allowlist: https://aayushgarg.dev/*, https://garg-aayush.github.io/*,
http://localhost:*/*
2. Generate WAQI token at aqicn.org/data-platform/token
3. Add both as repo Secrets: MAPBOX_TOKEN and WAQI_TOKEN
4. Local map preview (optional): in the browser console at localhost:4321, run
localStorage.setItem('iwMapboxToken', 'pk....') and reload
5. Push branch and bootstrap data: git push -u origin india-weather, then in
GitHub Actions UI run "India Weather Data" workflow on the india-weather
branch once to create the data branch
6. Verify https://raw.githubusercontent.com/garg-aayush/garg-aayush.github.io/
data/weather.json returns valid JSON
7. Open PR to master — the existing publish workflow will sed in the token and
ship the page
Branch is ready when you are.
✻ Brewed for 20m 27s
※ recap: Building the India Weather tab on your portfolio is done locally on the india-weather branch with five commits and a working preview at localhost:4321. Next: add MAPBOX_TOKEN and WAQI_TOKEN as repo secrets, then push the branch and run the cron workflow once to bootstrap the data branch. (disable recaps in /config)

⎿  Received 20.2KB (200 OK)
⏺ Mapbox's URL restrictions don't use wildcards — they want bare domains.
Subdomains and protocols are auto-allowed when omitted.
Correct entries to paste
Replace what's in the box with these three (bare hostnames, comma-separated):
aayushgarg.dev, garg-aayush.github.io, localhost
Why these:
- aayushgarg.dev — your custom domain (the CNAME file in your repo points
here)
- garg-aayush.github.io — the GitHub Pages origin, used as a fallback and
during deploys before DNS settles
- localhost — for quarto preview on any port (port restrictions are optional,
so omitting the port covers 4321 and any other you might use)
No https:// prefix needed — leaving the protocol off lets the token work over
both HTTP (localhost) and HTTPS (production). No /* paths — subdomains and
paths are auto-allowed once you specify the domain.
I'll also update the plan file to reflect the correct format so we don't
mislead anyone reading it later.
⏺ Updated plan

comma-separated), the validation error clears and "Create token" enables.

※ recap: Building the India Weather page (live temp + AQI for 8 metros, Mapbox map, leaderboard) is fully implemented and verified locally on the india-weather branch. Next: finish creating the Mapbox token using the bare-hostname format (aayushgarg.dev, garg-aayush.github.io, localhost) so we can add it as a GitHub Secret and push. (disable recaps in /config)
❯ What is the exact command that I should run in localhost console.
⏺ The exact command to run in the browser console at
http://localhost:4321/india-weather.html:
localStorage.setItem('iwMapboxToken', 'pk.YOUR_TOKEN_HERE');
location.reload();
Replace pk.YOUR_TOKEN_HERE with the token Mapbox just gave you (starts with
pk.). The location.reload() at the end picks up the stored token immediately.
You only need to do this once per browser, since localStorage persists.

Quarto preview is still running at http://localhost:4321/india-weather.html —
feel free to poke around it directly. When you're ready, the next steps are:
1. Add MAPBOX_TOKEN and WAQI_TOKEN as repo Secrets on GitHub
2. git push -u origin india-weather
3. Run the "India Weather Data" workflow once manually on the india-weather
branch to bootstrap the data branch
4. Open PR to master, merge
✻ Cogitated for 4m 9s
❯ Do we need to run the workflow manually? How will it work once we merge it to
the master branch?
⏺ Good question. Short answer: manual trigger is optional once we trust the
workflow. Here's the full lifecycle.
Important GitHub Actions rule
Scheduled workflows only run from the default branch (master). While we're on
the india-weather feature branch, the cron: */15 * * * * will NOT fire on its
own — even though the workflow file exists on the branch. Only
workflow_dispatch (manual) works on non-default branches.
This means the manual trigger before merging is the only way to test the cron
workflow without first merging it to master.
Two paths
Path A: manual trigger before merge (the cautious one)
1. Push india-weather to remote
2. Add WAQI_TOKEN and MAPBOX_TOKEN as repo Secrets
3. GitHub Actions UI → "India Weather Data" → Run workflow → branch:
india-weather
4. Verify it succeeded, data branch was created, JSON looks valid
5. Open PR, merge
Why bother:
- Catches a bad WAQI token, a bbox that returns zero stations, or a typo in
the workflow YAML before it lands on master
- Bootstraps the data branch so the very first visitor after merge already
sees real data instead of falling back to the bundled fixture for the first
~15 minutes
Path B: merge directly, let cron bootstrap itself
1. Push india-weather
2. Add the two Secrets
3. Open PR, merge to master
4. The cron now lives on master. Within at most 15 minutes (often less, but
GitHub queues can drift), the workflow fires for the first time, creates the
data branch, and visitors start getting real data
5. In the gap between merge and first cron run, visitors see the bundled
weather.sample.json fixture (the client falls back automatically when the
remote URL 404s) — they get a working page with stale-but-plausible data, not
an error
Both paths end in the same steady state.
Steady state after merge
- Every ~15 minutes, the cron fires on master, runs the fetcher, force-pushes
a new weather.json to the data branch
- The published site at aayushgarg.dev/india-weather.html is unchanged — no
redeploy needed for data updates
- Visitors fetch the JSON directly from
raw.githubusercontent.com/.../data/weather.json
- Updates are completely decoupled from your normal git push to master flow.
You can leave the site untouched for months and the data keeps refreshing
My recommendation
Path A. It's 30 seconds of extra work and it lets you verify the WAQI token
actually returns CPCB station data before any visitor hits the page. If
something's wrong with the token or a city's bbox, you'd rather find out from
a manual run than from a PR-monitoring badge after merge.
✻ Worked for 32s
❯ Don't see the india-weather data workflow in GitHub actions UI.
⏺ The workflow file only appears in the Actions UI once GitHub has seen it on a
remote branch. We haven't pushed yet — that's almost certainly why.

---log vs remote---
⏺ The branch is pushed (origin/india-weather is at the same commit as local).
The reason you don't see the workflow in the Actions UI is a GitHub quirk:
Workflows only appear in the Actions UI sidebar after they've existed on the
default branch (master) at least once. Since this workflow is only on
india-weather, GitHub's UI hides it. The file is otherwise valid.
You have three options:
⏺ Bash(gh workflow list --all 2>&1 | head -10 && echo "---try by file---" && gh
workflow view india-weather-data.yml --ref india-weather 2>&1 | head -10)

⎿  HTTP 404: workflow india-weather-data.yml not found on the default bra
nch (https://api.github.com/repos/garg-aayush/garg-aayush.github.io/ac
tions/workflows/india-weather-data.yml)
⏺ Confirmed. GitHub's API explicitly returns workflow not found on the default
branch. This is GitHub's actual rule, not a UI bug:
▎ A workflow file must exist on the default branch (master) before it can be
▎ triggered via workflow_dispatch from any branch, and before it appears in
▎ the Actions sidebar.
Even though the file is on india-weather, GitHub won't let us run it until
it's also on master. So Path A (manual trigger before merging) isn't actually
possible here.
Practical options
Option 1: Merge and let cron bootstrap (simplest, lowest friction)
1. Open PR india-weather → master, merge it
2. The publish workflow renders + ships the page; the cron workflow now lives
on master
3. Within ~15 min the cron fires for the first time, creates the data branch,
populates weather.json
4. Visitors who hit the page in that ~15 min window see the bundled fixture
(the JS fallback handles the 404 silently)
5. After first cron run, real data flows
Risk if the cron has a bug: page keeps showing fixture data; you fix in a
follow-up commit. The site never breaks.
Option 2: Two-PR split (paranoid, more work)
1. PR #1: workflow file only → master. Merge.
2. Now workflow shows up in Actions UI. Run it manually, verify data branch
populates correctly with both Open-Meteo and WAQI working
3. PR #2: everything else → master. Merge.
This costs you two PRs and two reviews for the safety of catching a token /
bbox issue before the feature is user-visible.
My recommendation
Option 1. We already verified the fetcher script works against Open-Meteo
locally (got real data for all 8 cities). The only unknown is WAQI, and the
fetcher is designed to degrade gracefully if WAQI returns nothing — you'd just
see aqi: null for affected cities, not a broken page. The 15-minute
fixture-fallback window after merge is invisible to users in any meaningful
way.
Want me to open the PR? I'd write ## Summary bullets per your repo conventions
and skip the test-plan section.

Done
- PR #57 merged at commit 74d58e0 (squashed)
- Publish workflow running now — will render the page and ship it to gh-pages
with the Mapbox token sed'd in (assuming MAPBOX_TOKEN secret is set)
- India Weather Data workflow registered but has 0 runs so far — its first
scheduled run will fire within the next 15 minutes and bootstrap the data
branch
What you need to do next
1. Add the two repo Secrets if not already done: MAPBOX_TOKEN and WAQI_TOKEN
at
https://github.com/garg-aayush/garg-aayush.github.io/settings/secrets/actions
2. Trigger the data workflow once manually (now that it's on master, the UI
works): https://github.com/garg-aayush/garg-aayush.github.io/actions/workflows
/india-weather-data.yml → Run workflow. This bootstraps the data branch
immediately instead of waiting up to 15 min.
3. Watch the publish workflow finish:
https://github.com/garg-aayush/garg-aayush.github.io/actions
4. Visit https://aayushgarg.dev/india-weather.html once gh-pages updates
(usually 1-2 min after the publish workflow succeeds)
If anything breaks I can investigate, but with the fixture fallback the worst
case is "page shows fixture data" rather than a broken page.

❯ How to resolve [Image #2]
⎿  [Image #2]
⏺ GitHub's secret scanner blocked the publish push because it detected the
Mapbox token (any pk.* matches GitHub's "Mapbox Access Token" pattern,
regardless of whether Mapbox itself classifies it as public). The token got
sed'd into _site/static/india-weather/india-weather.js and then quarto tried
to push that to gh-pages, which is a tracked repo branch, so push protection
kicked in.
Two ways to resolve this. They're meaningfully different and worth choosing
carefully.
A. Click the unblock URL (quick, ~2 min)
https://github.com/garg-aayush/garg-aayush.github.io/security/secret-scanning/
unblock-secret/3CzrQ1tANWo1JM8htzbZJctaSrW
Pick "I'll accept the risk" or similar, give a short reason ("Public Mapbox
pk.* token, URL-allowlist restricted to my domains"). Then re-run the failed
Publish workflow. GitHub remembers this specific token and stops blocking it
on future pushes.
Tradeoffs:
- Fast.
- The token still lives in gh-pages, which technically violates your "no
tokens in any repo branch" rule. We're treating gh-pages as "published
artifact" rather than "source", which is a defensible distinction but not a
strict one.
- If you ever rotate the Mapbox token, you'll hit this dance again with the
new value.
B. Switch to Leaflet + CartoDB Dark Matter (clean, ~30 min, recommended)
Drop Mapbox entirely. Use Leaflet with CartoDB's free Dark Matter tiles. No
token anywhere, no sed step in the publish workflow, no localStorage fallback
for local dev, no GitHub scanner blocking, no Mapbox URL-allowlist setup, no
token rotation concern.
Tradeoffs:
- Slight visual difference: CartoDB Dark Matter is raster tiles (vs Mapbox's
vector tiles), so labels are less crisp on retina and you can't dynamically
restyle. For a static map of 8 dots, the difference is small.
- Genuinely consistent with your "no tokens, anywhere, ever" rule.
- All the existing logic (markers, popups, leaderboard, fitBounds, mobile
layout, fixture/remote data loading) translates directly. ~150 lines of JS
change shape but keep the same behavior.
- We can revert the publish workflow's sed step too, simplifying CI.
My recommendation
B. Your stated preference was "never commit any token... even client-side
public ones." A is a one-time workaround; B actually upholds the rule. The
publish workflow becomes simpler, not more complex. And the Mapbox
URL-allowlist setup you started becomes unnecessary.
Want me to do B? I'd tear out Mapbox cleanly, swap to Leaflet, undo the sed
step in quarto-publish.yml, push to a new feature branch, PR + merge, and
verify locally before pushing.
✻ Cogitated for 1m 56s
❯ For now, I have gone ahead with the option A. Tell me what is the
vulnerability and security issue if we have the token as live in GH pages.
⏺ Honest analysis. The short version: for a pk.* token with URL restrictions on
a personal portfolio, the realistic risk is "someone could make me a slightly
bigger Mapbox bill if they really tried", not "someone could compromise my
account or data".
What the token can and cannot do
Mapbox has two token types and they are not equivalent:
┌───────────┬───────────────────────────────────┬────────────────────────┐
│ Type │ Default scopes │ Can abuse? │
├───────────┼───────────────────────────────────┼────────────────────────┤
│ pk.* │ styles:read, fonts:read, │ Read-only against │
│ (yours) │ tiles:read, datasets:read │ Mapbox's APIs │
├───────────┼───────────────────────────────────┼────────────────────────┤
│ │ Can include tokens:write, │ Account-level damage, │
│ sk.* │ styles:write, tilesets:write, │ data destruction, │
│ (secret) │ uploads:write, account-level │ token forging │
│ │ scopes │ │
└───────────┴───────────────────────────────────┴────────────────────────┘
A leaked pk.* token cannot modify your account, edit your styles, create or
delete data, generate new tokens, or read anything that is not already public.
It can only call Mapbox's read APIs as if it were you.
The actual realistic risks
1. Quota / billing inflation. Someone copies the token and uses it to make map
tile requests. Mapbox's free tier covers 50,000 map loads per month. Above
that, you pay roughly $5 per 1000 loads. A determined attacker spoofing your
Referer header could run up usage on your account.
Mitigation that already applies:
- The URL allowlist (aayushgarg.dev, garg-aayush.github.io, localhost) blocks
naive abuse. A request from another domain returns 401 unless the attacker
actively spoofs the Referer header.
- Spoofing requires running requests from a server, not from a normal browser.
Possible, but not a drive-by attack.
Mitigation worth adding (5 minutes, do this):
- In your Mapbox dashboard, set a monthly usage limit / spending cap. For a
portfolio that gets a few hundred visits a month, cap it at something like
10,000 loads or $5. If anyone (you or an attacker) blows through it, the token
starts returning 429 instead of charging your card. You will not get a
surprise bill.
2. Rate limiting affecting your real users. If someone is hammering the token,
Mapbox may rate-limit the token itself, which means your visitors briefly see
a broken map. You rotate the token, you recover.
3. Pattern-matching abuse. Bots scrape GitHub for tokens and try them. Most of
these are looking for sk.* and AWS keys; a pk.* is much lower-value. The URL
allowlist neutralises most of these.
What a leaked pk.* cannot do
- It cannot read your Mapbox account email, billing info, or account settings.
- It cannot create new tokens or change scopes on existing ones.
- It cannot read or write data in any account-private tilesets or datasets.
- It cannot affect anything outside Mapbox.
- It cannot pivot to other systems. The token only authenticates to Mapbox
APIs.
How this compares to a real leak
If an sk.* token had ended up in gh-pages, the picture is very different. An
attacker could regenerate all your tokens, delete your custom map styles,
exfiltrate private datasets, and lock you out of your own Mapbox account. That
is the kind of leak that warrants alarm. A pk.* is one or two steps above
leaking your public Twitter handle in a config file: technically it is
information that should not have been there, but the blast radius is small and
bounded.
Why GitHub blocked it anyway
GitHub's secret scanner uses regex patterns and cannot reliably distinguish
pk.* from sk.* (both are JWTs with similar structure). It flags both because
conservative defaults are correct policy for the typical case, where sk.*
exposure would be catastrophic. For pk.* specifically, the protection is a
false positive in spirit: this token is designed to be public.
Concrete actions worth doing now
1. Mapbox dashboard → set a hard spending cap and a usage alert. This is the
single most important step.
2. Confirm URL allowlist saved correctly with aayushgarg.dev,
garg-aayush.github.io, localhost (no wildcards).
3. Once a month, glance at your Mapbox usage chart for anything weird. If you
ever see usage you cannot explain, regenerate the token; takes 30 seconds.
4. Long-term, if it ever bothers you, the Leaflet swap is still there as a
clean exit. Not urgent.
You are not in a worrying position. You are in the position Mapbox's token
model expects you to be in: a public read-only key, scoped, restricted,
monitorable, rotatable.
✻ Cogitated for 59s
※ recap: We shipped the new India Weather page (Mapbox map plus AQI leaderboard for 8 metros) and merged PR #57; you bypassed GitHub's secret scanner block on the Mapbox pk token. Next: re-run the failed Publish Quarto Site workflow so the page goes live. (disable recaps in /config)

⏺ Diagnosed. The cron has only run once (the manual trigger we did at
18:00:20Z). It is now 18:19Z, and GitHub's scheduled */15 should have fired at
18:15Z, four minutes ago. It did not.
This is classic GitHub Actions cron behavior, and it is documented:
Why scheduled runs are unreliable, especially the first ones
1. First-run delay. Newly registered scheduled workflows often take 30 to 60
minutes before GitHub's scheduler starts honouring them. The scheduler has its
own discovery loop that is not synchronous with workflow registration. Your
workflow was added to master 19 minutes ago, which is squarely in this lag
window.
2. Best-effort execution. From GitHub's own docs: "The schedule event can be
delayed during periods of high loads of GitHub Actions workflow runs. High
load times include the start of every hour." Top-of-hour and quarter-hour
ticks (*/15) are exactly when load is highest, so these are the most likely to
be delayed or dropped.
3. Public free repos get lower priority. Scheduled workflows on free public
repos can be silently deprioritized when the runner pool is congested.
4. */15 does not mean "every 15 minutes from when it last ran". It means "fire
at minute 0, 15, 30, 45 of every hour" against GitHub's scheduler clock. So
the next attempted fires are 18:30Z, 18:45Z, 19:00Z, etc., not 15 minutes
after the manual run.
What you should expect: scheduled runs become reliable after the first hour or
two, but even then, GitHub will occasionally drop one. For a portfolio site,
this is acceptable; the page never breaks because of the fixture fallback and
short cache TTLs on raw.githubusercontent.com.

⏺ Diagnosed fully. Two compounding causes, plus the cache-bust trick I built in
does not actually work on this endpoint.
What actually happened
1. The scheduled cron has not fired since merge. GitHub Actions' scheduler has
a documented lag of 30 to 60 minutes for newly registered schedules. The
first scheduled tick after a workflow lands often gets dropped silently. We
saw zero scheduled runs between 18:00Z and now (18:21Z); the only run on data
branch was your manual trigger.
2. I just triggered another manual run (18:19:51Z, completed 18:20:31Z). The
data branch now has commit a030644f with generated_at: 18:20:26Z. So fresh
data exists on GitHub.
3. raw.githubusercontent.com has a 5-minute Fastly cache in front of it. Even
though the new commit is on data, Fastly is still serving the response from
the previous fetch (x-cache: HIT, cache-control: max-age=300) until that
5-minute window elapses. Your browser hits Fastly, Fastly returns the old
payload.
4. My cache-bust query string does not work here. I had forceFresh ? base +
'?t=' + Date.now() : base in the Refresh button. Fastly's raw-content cache
does not vary by query string, so adding ?t=... returns the exact same cached
response. I tested it just now: same x-cache: HIT, same old content. The
Refresh button is therefore a no-op until Fastly's TTL expires.
What this means for real users
The total worst-case staleness is roughly cron interval + Fastly TTL = 15 + 5
= 20 minutes. This is fine for a weather dashboard (the upstream sources
update at most every 10 to 15 minutes anyway), but the Refresh button
overpromises right now. It looks interactive but it does not actually force a
re-fetch from origin.
What to do
Right now (one-time), to see the fresh data:
- Wait about 4 more minutes for Fastly's 5-minute TTL to roll over from the
previous cached response, then hard-reload (Cmd+Shift+R).
- Or open the page in an incognito tab in 4 minutes.
Going forward, two improvements worth making, both small:
Fix the broken Refresh button. Use If-None-Match with the previously seen
ETag, or fetch via jsDelivr's commit-pinned URL which does honor cache-bust.
Easiest practical fix: switch the data URL to jsDelivr (https://cdn.jsdelivr.n
et/gh/garg-aayush/garg-aayush.github.io@data/weather.json). jsDelivr's cache
invalidates within seconds of a new commit on the branch, so the worst-case
staleness drops from ~20 min to ~15 min, and the Refresh button starts
behaving as users expect.
Set realistic expectations in the subtitle. Change "Refreshed every 15 min" to
"Refreshed every ~15 min (data may lag up to 20 min)". This is more honest
about GitHub Actions cron drift and edge caching.
Want me to make either of those fixes? The jsDelivr swap is a one-line change
in india-weather.js plus a quick local verification.

76 +## Live Data Pages
77 +
78 +Pages that fetch data refreshed by a cron workflow rather than
+ at build time. Currently just `india-weather.qmd`, but the pa
+ttern is reusable.
79 +
80 +### Files (India Weather)
81 +- `india-weather.qmd` — top-level Quarto page; embeds the Mapb
+ox CDN and the page skeleton via raw HTML
82 +- `static/india-weather/india-weather.js` — client renderer (M
+apbox markers, popups, leaderboard, fitBounds, fixture-fallbac
+k fetch)
83 +- `static/india-weather/india-weather.css` — page-specific sty
+les, reuses the global CSS variables from `styles.css`
84 +- `static/india-weather/cities.json` — city config (id, name,
+lat, lon, bbox); read by both the fetcher and the client
85 +- `static/india-weather/weather.sample.json` — hand-authored f
+ixture used as a fallback when the remote data branch is unrea
+chable
86 +- `scripts/fetch-india-weather.mjs` — pure-Node ESM fetcher (n
+o deps, uses built-in `fetch` and `AbortController`)
87 +- `.github/workflows/india-weather-data.yml` — `*/15` cron + `
+workflow_dispatch`
88 +
89 +### Architecture
90 +- The cron checks out `master`, runs the fetcher (which calls
+Open-Meteo for weather and WAQI for AQI), then publishes the r
+esulting `weather.json` as a single-commit force-push to an or
+phan `data` branch.
91 +- The published page reads `weather.json` from `https://raw.gi
+thubusercontent.com/garg-aayush/garg-aayush.github.io/data/wea
+ther.json`. If that fetch fails (404, offline), the JS falls b
+ack to the bundled `weather.sample.json` so the page never sho
+ws a broken state.
92 +- Visitor count never affects API call volume because all fetc
+hing happens server-side on the cron schedule.
93 +
94 +### Token handling
95 +- **No tokens in source, ever.** Both `MAPBOX_TOKEN` and `WAQI
+_TOKEN` live as GitHub repo Secrets.
96 +- `WAQI_TOKEN` is consumed inside the cron workflow only; neve
+r reaches the client.
97 +- `MAPBOX_TOKEN` must reach the client to render the map. The
+repo source has only a `__MAPBOX_TOKEN__` placeholder in `indi
+a-weather.js`. The publish workflow's `sed` step replaces it a
+fter `quarto render` and before pushing to `gh-pages`. Local d
+ev falls back to `localStorage.iwMapboxToken` so the token nev
+er touches a shell history or dotfile either.
98 +- Mapbox URL allowlist on the token: `aayushgarg.dev`, `garg-a
+ayush.github.io`, `localhost`. Bare hostnames only; Mapbox doe
+s not accept wildcards or path suffixes.
99 +
100 +### Known caveats
101 +- **GitHub Actions cron drift.** Scheduled runs are best-effor
+t. The very first scheduled tick after a workflow is registere
+d often does not fire for 30 to 60 minutes, and `*/15` runs ca
+n be delayed or dropped under load. The page handles this grac
+efully (the client shows a relative `Updated Nm ago` timestamp
+ from `generated_at`), and `workflow_dispatch` is available fo
+r manual force-refresh.
102 +- **`raw.githubusercontent.com` Fastly cache.** Responses are
+cached for ~5 minutes, and Fastly does NOT vary the cache by q
+uery string. The current Refresh button cache-busts with `?t=D
+ate.now()` but Fastly ignores it; the button effectively only
+re-renders the existing cached payload. Worst-case staleness i
+s therefore cron interval (15 min) plus Fastly TTL (5 min) ≈ 2
+0 min. Acceptable for portfolio purposes; switch to jsDelivr i
+f a tighter SLA is ever needed.
103 +- **GitHub secret scanning.** Push protection flags any `pk.*`
+ Mapbox token landing in any branch (including `gh-pages`). Th
+e first push after rotating the Mapbox token will be blocked o
+nce and require a click-through unblock URL. Pasting a `pk.*`
+directly into source instead of the placeholder will be perman
+ently blocked.
104 +- **Mapbox token type.** Use `pk.*` (public, scoped read-only)
+. Never put an `sk.*` token anywhere near the client.
⏺ Updated CLAUDE.md with three additions:
1. CI/CD section now describes the sed-token-injection step in the publish
workflow and the new india-weather-data.yml cron workflow.
2. Content + Navbar now lists india-weather.qmd as a top-level page and the
navbar order includes "India Weather" between Tools and Publications.
3. New "Live Data Pages" section at the bottom captures the reusable pattern:
file inventory, the cron-to-orphan-data-branch architecture, the
no-tokens-in-source token handling rule, and the known caveats around GitHub
Actions cron drift, Fastly's 5-min cache, secret scanning, and the pk.* vs
sk.* distinction.
I left the file uncommitted since you already had local edits in flight (the
categories field rules and the parallel-worktree comparison note). Review the
diff with git diff CLAUDE.md and commit when you are ready.
